找不到坠机试飞的原因 [英] Can not find reason for crash test flight
本文介绍了找不到坠机试飞的原因的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我的一位测试飞行测试人员刚刚报告了一次坠机。我已经花了两个月的时间思考为什么它让他们和其他人崩溃。我无法自己复制崩溃信息，因此必须在使用iTunes connect的情况下通过试飞系统提交新的构建，并等待用户对其进行测试，然后才能知道我是否取得了进展。这是一个非常缓慢且乏味的过程，因此，我在这里恳请您提供知识，并帮助我先了解为什么该应用程序仅针对该用户（共12位）崩溃。
Just one of my test flight beta testers has reported a crash. I have for 2 months now been scratching my head as to why it crashes for them and no others. I am unable to replicate the crash myself so have to submit a new build through the test flight system with iTunes connect and wait for user to test it before I know if I have made progress or not. This is very slow and tedious process and so I am here to plead you for your knowledge and help me first understand why the app crashes only for this one user (of 12) .
我从试飞中获得的崩溃报告是

崩溃报告指示的行是
let cell = self.tableView.dequeueReusableCellWithIdentifier（ meetUp，
forIndexPath：indexPath）一样！ MeetUpDisplayTableViewCell

您能从此崩溃日志中看到原因吗？
专业化是什么意思？
Can you see the reason from this crash log? What does "specialised" mean?
非常感谢您的帮助
如果您有否决这个问题。干得好但是请足够勇敢地说出原因
If you have to vote this question down. Well done you. But please be brave enough to say why
更新：
因此，我安装了fabricrashlytics并在代码中添加了代码以找出我到底崩溃了。从日志中看来，我尝试设置单元格的属性时就会崩溃。尽管如上所述，这只是一个用户的问题。有什么建议么？非常感谢
UPDATE: So I installed fabrics crashlytics and peppered my code my logs to find out where exactly i was crashing. From the logs it appears I am crashing as soon as I try to set a property of the cell. This though as mentioned is only an issue for one user. Any suggestions? Many thanks
推荐答案
已解决：
在使用Fabrics Crashlytics之后，一行一行地发现应用程序在这里崩溃
After using Fabrics Crashlytics and going line by line I discovered that the app was crashing here
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
//changed this
//dateFormatter.timeZone = NSTimeZone.systemTimeZone()
//to
dateFormatter.locale = Locale(localeIdentifier: "en_GB")
if let eventDateString = JSONDict["EventDateTime"] as? String {
let eventDate = dateFormatter.dateFromString(eventDateString)
let calendar = NSCalendar.currentCalendar()
let components : NSDateComponents = calendar.components([NSCalendarUnit.Year,NSCalendarUnit.Month,NSCalendarUnit.Day,NSCalendarUnit.Hour,NSCalendarUnit.Minute,NSCalendarUnit.Weekday], fromDate: eventDate!)
长话短说，当用户设备使用12小时格式而不是24小时格式时，会发生崩溃。
long story short the crash occurs when users device is using the 12 hour format and not 24 hour.
